Compact package and Superior design of the AccuRingrotary stages wasoptimized to minimize stage height. The low profile of the stage reducestotalsystem working height. Angular contact bearings are used to maximizeperformance withrespect to wobble, moment stiffness and friction. AccuRing stage haslarge clearcenter aperture that can be used for air or wire line feed-through orbeam delivery.

AccuRing utilizes direct drive three phase brushless motortechnology. There are no brushesto replace and no gear trains or belts to maintain. Coreless magneticdesign assures smooth rotation and dynamic performance.

Accurate Positioning is assured with contact-less encoder. The motor and rotary encoders are directlycoupled to eliminate coupling backlash. The low inertia and zero backlash make AccuRing the ideal solution for applications requiring frequent directional changes.
